The Royal Regiment of Horse Guards (The Blues) (RHG) was a cavalry regiment of the British Army, part of the Household Cavalry. Raised in August 1650 at Newcastle upon Tyne and County Durham by Sir Arthur Haselrigge on the orders of Oliver Cromwell as a Regiment of Horse, the regiment became the Earl of Oxford's Regiment in 1660 upon the Restoration of King Charles II. As, uniquely, the regiment's coat was blue in colour at the time, it was nicknamed "the Oxford Blues", from which was derived the nickname the "Blues." In 1750 the regiment became the Royal Horse Guards Blue and eventually, in 1877, the Royal Horse Guards (The Blues).
